Hi,

Hi, I would like to know if it is possible to measure/show the curent/power flow direction on Sentron PAC. I've got some extracts from the manual, but I'm still unsure about it:

"Measured values, limit value violations, operating hours of a connected load or power flows are supplied by the instruments quickly and reliably. " and

"For measuring currents it is possible to use both x/1A and x/5A current transformers (for 7KM PAC3100 only x/5A x/5A current transformers). Transformer ratios and current direction can be programmed on the device for adaptation to local conditions."

Thanks in advance.

.TT,

it is possible to measure energy and power in both directions (kW/kvar/kWh/kvarh Import and Export). Data is available on local display, as well as in standard communication maps (Profibus, Profinet).

Hope this helps.

Regards.

Is it shown as an arrow, for example? The client wants to know whether the current is going "upwards" or "downwards".

Thank you.

.TT,

I suppose your client wants to see arrows for positive/negative power direction. I don't think that's possible with PAC3200. If my memory serves me well, you have a button to exchange Import/Export power values on the screen, and also minus sign for negative direction.

From PAC3200 manual:

"Please take account of the direction of current flow when connecting the current measuring inputs. With inverse connection, the measured values are inverted and receive a negative sign."

Hope this helps.

crazyCow,

It has certainly helped me. Thanks a lot!
